2/29/2024 0 Comments Bejeweled 2 play online![]() ![]() Now we're into the 21st century of video games and the technology has advanced farther with more diversion of gameplay available. You know when I first started out playing Tetris, it got boring and repetitive after awhile. If you want a very simple puzzle game to play every once in a while for five minutes then Bejeweld might be worth a shot, but it shouldn't be hard to find something better. There is not much to say about Bejeweld: It looks decent and it plays decent, but nothing special. Unlike most simple games like Dear Runner and Mario there is just nothing that actually makes me want to play it. Once I get playing it's fun for a few minutes and then I go back to work. I only play this game every once in a while when I am bored, but never because I actually want to. It is incredibly simple and there is barely anything special. I have witnessed moments when I racked up highscores just because the explosions kept coming. The game often plays itself, after you take out a few blocks new ones appear on the top and that means those blocks can also disappear when they drop next to the same kind. The producers apparently used random images from Google for their background because there is a lot of uninspiring and pixelated scenery pictures in the back. The game is also very colorful and that is always a plus in my book. The explosions and electricity are fun to watch and clearly used to appeal to the youth. Personally I also enjoyed moving the shapes around and watching them explode and getting four or five of them in a row is always exciting. This game is for all ages and both my younger sister and my grandmother said the game was fun and challenging at times. ![]()

2/29/2024 0 Comments Intensity equation light chemistry![]() ![]() One of the most common application of infrared spectroscopy is to the identification of organic compounds. However, the utility of the fingerprint region is that the many bands there provide a fingerprint for a molecule. The fingerprint region is often the most complex and confusing region to interpret, and is usually the last section of a spectrum to be interpreted. Many different vibrations, including C-O, C-C and C-N single bond stretches, C-H bending vibrations, and some bands due to benzene rings are found in this region. ![]() This region is notable for the large number of infrared bands that are found there. The region of the infrared spectrum from 1200 to 700 cm -1 is called the fingerprint region. Group frequency and fingerprint regions of the mid-infrared spectrum These types of infrared bands are called group frequencies because they tell us about the presence or absence of specific functional groups in a sample.įigure 2. This makes these bands diagnostic markers for the presence of a functional group in a sample. For example, C-H stretching vibrations usually appear between 32cm -1 and carbonyl(C=O) stretching vibrations usually appear between 18cm -1. However, in a mixture, two peaks may have different intensities because there are molecules present in different concentration.Īn important observation made by early researchers is that many functional group absorb infrared radiation at about the same wavenumber, regardless of the structure of the rest of the molecule. For pure sample, concentration is at its maximum, and the peak intensities are true representations of the values of ¶ µ/ ¶ x for different vibrations. The absorptivity is an absolute measure of infrared absorbance intensity for a specific molecule at a specific wavenumber. The absorptivity is the proportionality constant between concentration and absorbance, and is dependent on ( ¶ µ/ ¶ x) 2. The equation(5) that relates concentration to absorbance is Beer's law, The change in dipole moment with respect to distance for the C-H stretching is greater than that for the C-C rock vibration, which is why the C-H stretching band is the more intense than C-C rock vibration.Īnother factor that determines the peak intensity in infrared spectra is the concentration of molecules in the sample. One of the weaker bands in the spectrum of octane is at 726cm -1, and it is due to long-chain methyl rock of the carbon-carbon bonds in octane. For example, the most intense band in the spectrum of octane shown in Figure 3 is at 2971, 2863 cm -1 and is due to stretching of the C-H bond. \) is different for each of these vibrations. ![]() ![]() ![]() Free Tool: You can download and convert Youtube to mp4 for free without any feature limitation.

Innovative product: Your new product doesn't have direct competition or reference price. Here are situations when you may consider using the skimming pricing strategy: Price elasticity and their target customer can also influence their choice of strategy. Their decisions may be influenced by factors such as production capacity restrictions or the ability to perform mass production. This allows you to minimize your costs.Ĭompanies opt for skimming or penetration depending on what they want to maximize: market share, total profit, customer lifetime value or profit margin. Selling many items may allow you to order supplies in bulk and receive discounts from suppliers. Lower costs: When you offer a low selling price, you can generate a high sales volume. Reduced competition: Penetration creates a barrier to entry, meaning it can prevent competitors from entering your market, because they can’t offer a price lower than yours. The low price brings them in, and depending on your product’s quality, customers might keep buying it even if you increase the price later. Improved brand loyalty: In the midterm, penetration pricing allows you to build a strong and loyal customer base. The penetration strategy offers the following benefits:Ĭustomer conversion: Penetration can help you attract customers away from competing brands, if you pair the product launch with efficient marketing. Then, according to your customers' behavior, you might adjust and reduce the price. You start high and identify your consumers' price sensitivity while selling as much as possible at the highest price. Īdaptable strategy: The skimming strategy offers the possibility to change the price according to market changes. Companies often see customers associating their products with terms like “prestigious,” “innovative,” “unique or “futuristic,” because customers often perceive expensive products as high-quality products. Improved brand image: Skimming can influence the way customers perceive your brand. This results in high revenue and profit you might use to increase marketing efforts and distribution, boosting profit even more. Maximized early revenue: When you use the skimming pricing method, you can cover your investment costs rapidly as you sell at the highest possible price. Therefore, you can maintain high prices and generate stable profits in the long term. Steady long-term profit: Skimming allows you to target value-oriented customers who are willing to spend more money. Low cost impact: Skimming allows you to generate a profit margin regardless of the cost basis because your price is high. Price skimming can offer the following benefits: Skimming and penetration pricing strategies offer different benefits, including:: Skimming benefits Read more: What Is Penetration Pricing Strategy? (Plus Examples) Differences between skimming and penetration pricing Doing so, they manage to keep their prices low and keep their customers. Companies often use this strategy combined with a low-cost structure, meaning they reduce costs to maximize margins. When setting a low price as part of an introductory campaign, companies may find customers switch to competitors once the price is raised. However, penetration pricing may continue to see limited profits because the company doesn't target customers willing to pay high prices. Finally, when the demand increases, you can set the price higher. Profits are lower in the short term, but the high number of early sales compensates for the small margins. With this method, you enter the market rapidly and grow a loyal client base. Penetration pricing is a strategy where prices are set low to attract new customers and increase the product’s market share. Related: How To Set a Pricing Strategy Framework What is penetration pricing? Therefore, a high-quality product is essential to maintain your value-oriented customers' interest. Skimming leaves an opportunity for competitors to undercut your prices and try to attract your customers. The price is then steadily reduced over time to attract other customers. You make fewer sales at first, but they are more profitable. ![]() Price skimming is an effective pricing strategy when companies target customers that are already interested in their products The strategy is to set your prices high in the beginning to maximize short-term profits. ![]() ![]() ![]() You can now enjoy Home DVD movies, videos, YouTube videos, music on your iPhone, iPad, iPod, Apple TV, Galaxy, HTC One, Moto X, Nexus, Kindle, Surface, Lumia and any MP4/MP3/DVD/CD players.

Although it’s not as common in Utah as in other states, cases and reports of infected lakes continue to increase enough to warrant caution. The parasite responsible lives in ponds, lakes, and even oceans. Swimmer’s itch is an allergic reaction and rash caused by microscopic parasites burrowing into your skin. Before you go, check whether that lake is infected with cercarial dermatitis, better known as swimmer’s itch. Summertime has arrived, and you’re looking forward to a day out on the lake. Be cautious of lakes and ponds that have snails and waterfowl.Several Utah waterways have had positive cases of swimmer’s itch.Swimmer’s itch is an allergic reaction from parasites that may cause irritated skin.However, repeated exposures can result in severe reactions.Swimmer’s Itch What is it and how can you treat it? July 20, 2022 Swimmer’s itch usually resolves within 1–3 weeks without treatment. Short course of oral corticosteroid for a severe reaction.Immediate towelling after exiting the water to reduce skin penetration of the parasites.To reduce the risk of cercariae on the skin: Use of chemical molluscicides such as copper sulphate or copper carbonate in small lakes to kill potentially infested snails.Reduce vegetation in high-risk areas to make the environment less favourable for the water snails.Feed birds with a drug to treat the parasite.To reduce parasite numbers in the environment: What is the treatment for swimmer’s itch? Preventative measures What is the differential diagnosis for swimmer’s itch? There is no widely available blood test to confirm an allergy to cercariae. Skin biopsies are not diagnostic but may be performed to exclude other causes of an itchy, blistering, or urticarial rash. Swimmer’s itch is suspected clinically based on the characteristics of the rash following bathing in infested waters. Secondary bacterial infection following scratching.Episodes become more severe with repeated exposures.What are the complications of swimmer’s itch? Outbreak of swimmer's itch in Denmark. Acta Derm Venereol. Cercariae may accidentally attach to human skin, penetrate the skin, die, and cause a local allergic reaction.Ĭredit: Images are from Tracz ES, Al-Jubury A, Buchmann K, Bygum A. Cercariae may penetrate the skin or are ingested by the aquatic bird/animal, develop into an adult worm, and the cycle starts again. The miracidium enters the snail, elongates into a sporocyst, then matures into a cercaria which burrows out of the snail into the water. An egg hatches in the water to become a free-swimming miracidium in search of a specific snail species. ![]() ![]() ![]() The adult worm lives in a bird/animal, and the eggs are excreted via the intestines in the faeces. Schistosomes are parasitic flatworms with a lifecycle that involves aquatic birds (eg, ducks, geese, gulls, swans) or mammals (eg, beavers, muskrats), specific species of aquatic snails, and warm fresh or salt water. Swimmer’s itch is a disease of aquatic birds and humans are accidentally affected. However, it is only after repeated exposure to cercariae that the allergy develops and a rash eventuates. Young children are particularly susceptible as they tend to remain in shallow warm water where the snails are found in the highest numbers. Swimmer’s itch can affect anyone swimming in waters with infested snails. ![]() 2/29/2024 0 Comments Ear training vs aural skills![]() ![]() ![]() So what about D minor?

Yet he probably only ever heard it in F# minor, because period pitch was about a semitone lower than today. We know G minor was a 'special' key for Mozart ( Sturm und Drang), at least in his symphonies - Little G minor and Great G minor. Is it "a work of passion, violence, and grief" (as most of us, like Charles Rosen, would deem it today) or merely possessing "Grecian lightness and grace" (according to Schumann).or even - as the great musicologist Donald Francis Tovey saw in it - the character of opera buffa?

2/28/2024 0 Comments California covid map![]() ![]() County in recent weeks, though we’re still well below peak COVID levels. Science & Medicine Are we in a summer surge? What to do if you get COVID now Still, those who are being hospitalized tend to be older and those who haven’t received a COVID-19 booster shot in the past year - meaning they are not considered “up to date.” Even those COVID-19 patients who have been hospitalized, Chin-Hong said, are generally requiring shorter stays than earlier in the pandemic. Generally speaking, Chin-Hong said many people who have been infected with the coronavirus this summer did not require hospitalization, likely because they were vaccinated, had been previously infected, or both. Regardless of the new mutations in Pirola, Chin-Hong said, the anti-COVID therapeutic drugs Paxlovid and remdesivir should remain effective. Based on what’s currently known, if Pirola does become dominant, “at some point, it may fuel another round of transmission, and may find people who are ‘no-vids’’’ - people who have never been infected - “or people who are more vulnerable to getting ill,” Chin-Hong said. ![]() Still, those infected with the Pirola subvariant have so far experienced generally mild symptoms, Chin-Hong said. Should we be wearing masks again?Īmid the latest coronavirus uptick in California, health officials reiterate the same advice: Masks work, but it’s a personal preference whether to wear them. ![]() But in some parts of Europe, Pirola now makes up perhaps 1% to 2% of cases, and the fact that it’s on more than one continent suggests it is spreading, Chin-Hong said.Ĭalifornia COVID-19 is ‘heating up all around’ this summer. ![]() thus far, and the subvariant has yet to be detected in Los Angeles County. Very few cases of Pirola have been identified in the U.S. “But again, sequencing always lags and not a ton of people are doing sequencing anymore around the world.” “And who knows if it’s even going to become ruler of the roost? It really hasn’t taken off so far that we know,” Chin-Hong added. “BA.2.86,” he said, “is so different that people worry that the vaccine in the fall won’t be a perfect match - but nevertheless, it will still protect people against serious disease.” Peter Chin-Hong, a UC San Francisco infectious-disease expert. Unlike more recently identified subvariants, which might have one or two mutations that distinguish them from earlier versions, Pirola has 36 distinct mutations from XBB.1.5, “which is making people raise their eyebrows,” said Dr. Updated versions and new vaccines for COVID-19, influenza and respiratory syncytial virus will be rolled out this fall. Unlike last year’s formulation, a bivalent vaccine that was designed against both the ancestral coronavirus strain and the BA.5/BA.4 Omicron subvariants that were circulating at the time, the upcoming vaccine will be monovalent, specifically designed against XBB.1.5.Ĭalifornia With coronavirus uptick, should I get a COVID shot?
